Definitions

• the invention relates to a method for querying and maintaining an automatic call number information in mobile communication systems.
• Every participant in a mobile or fixed telecommunication network knows the possibility of calling numbers. By dialing a specific number, the subscriber is connected to the directory inquiry, an operator reports who accepts the request for information, researches the associated directory number and notifies the subscriber.
• the disadvantage of this telephone number information is that if the subscriber provides inaccurate or incomplete information, it is not possible for the operator to determine the associated telephone number. This is not possible due to time and cost reasons alone.
• the object of the present invention is to propose a method for querying and maintaining automatic call number information in mobile communication systems, which enables more flexible and inexpensive information.
• An essential feature of the invention is the possibility of personal query and maintenance of an electronic telephone book with the help of short messages. The user himself maintains the respective information entry.
• the queried information data records are transmitted from the central office to the subscriber number specified in the querying short message.
• the information records are inseparable from the subscriber identity, e.g. B. is predetermined by the number are linked. Creating, querying, changing and / or information records is only possible for the authorized subscriber himself.
• the subscriber is authenticated to use the caller ID information advantageously by means of the authentication sequence specific to the mobile communication network, which is activated when the user logs into the mobile communication network.
• a major advantage of the invention is that the user himself has the possibility to create and manage telephone book entries himself and to call them up at any time and inexpensively via the short message service.
• a further advantage is that a flexible query syntax is proposed, by means of which it is possible to obtain the correct information with great certainty even with inaccurate or incomplete search queries.
• One aspect of the invention is the combination of question parameters and how they are used to generate the answers, particularly in the case of inaccurate or incomplete information. Since the query of the call number information takes place via a mobile terminal, the type of character input, which is generally somewhat uncomfortable for the user, must be taken into account via the keyboard.
• a query is entered in the form of a short message on the mobile terminal and transmitted to the central office.
• the sender information d. H. the calling subscriber's number is an implicit information within this short message.
• the answer consisting of one or more short messages, is transmitted to the subscriber at this call number contained in the querying short message.
• the query itself consists of at least one, but generally several search words.
• the order of the search words in the query message is essential because it influences the evaluation of the possible answers.
• a search word consists of a certain string. In general, all characters from the short message character set are permitted in the search word. Two characters play a special role.
• the separator is an example (Space) and the so-called joker in this context * ". The separator separates search words from each other. If the separator should appear in the search word, a special syntax must be followed, e.g. B. Two consecutive separators must be written.
• Joker * plays a special role. It stands for any character string Joker appear as a normal character in the search word, it must be written twice in succession
• An essential aspect of the invention is that a user can manage, create, change and / or delete his information records himself in the information database.
• the authentication sequence specific to the mobile radio network is used to authenticate this subscriber.
• a data entry in the information database is inextricably linked to the sender information. Any change to existing information entries can only be made by the same sender.
• the answer text is in the central office Alexander Berg "in a suitable manner linked to the sender's call number and the current date and possibly further information.
• a response set is generated in the information database, taking essentially into account the degree of correspondence of each potential answer with the query text and the best "records are sent as answers to the querying participant.
